Application ined March 14, 1921i.k serial No. 699,308.

To all whom t may concern:

Be it known that l, JOHN W. LANGLEY, citizen of the Dominion of Canada,residing at Canford, Nicola Valley, in the Province of BritishColumbia,Canada, have invented certain new and useful Improvements in Trap,NestsIJ ot' which the following is a specification.

This invention relates to a trap nest for domestic fowl, and is designed.to admit the bird thro-ugh one opening and allow it to pass outthrough-another opening after laying, the entrance door being closedwhen the exit door is opened, and vice versa, so that'the laying birdscan be separated from those not laying as the releaseoi' the exit dooris effected, not merelyby the birds presence on the nest, but by depositof an egg. n

A further provision is made 'for withdrawal of the eggs as laid toprevent them injuring one another during delivery.

The means by which these several objects are attained is fully set forthin the following' specification, reference being made to the drawings bywhich it is accompanied, in which: Y

Fig. 1 is a sectional elevation of the nest, the near side beingremoved.

Fig. 2 is a plan of' the nest-box below the y nest `frameand treadle,showing the provip treadle 8.

sion for delivery of the egg from the nest.

Fig. 3 isr an end elevation of the same in the direction of the arrow 3in Fig. 2.

. In these drawings 2 represents the bottom, 3 the sides and 4 the topof the boxlike frame within whichthe nest is supported. Pivotallymounted on a rod 5 between the sides 3 of this box frame is a nest frame6 carrying toward the front end a nest 7 and on the opposite side of thepivot an eXit Flexibly connected by straps 9 to the front endl of thenestframe 6 is the entrance door 10 which, adjacent its connection tothe nest frame, is pivoted on a rod 11 to a cross rail 12 between thesides 8 of the box frame, to assume a normally-horizontal open position,as shown by the full lines in Fig. 1, or an upright closed position, asby the dot and dash lines in the same ligure.

On the other side of the nest 7 an exit door 30y is suspended at 31`from the top 4 of'the` box frame, and is connected by a rod 32 to theentrance doorlO. With `this connection, as these doors open in oppositedirections, the exit door 30y opens, while the entrance door 10 closes,and vice versa.

Movement from the open to the closedv position of the door 10 is eiectedby depression olf' the end of `the nest frame 6, which is connected toit, as bythe weight of when in the nest 7, but" as it is not de--vrsii-ed `to effect they closing of the entrance door and the opening otthe exit door unless `the hen which occupies the nest first deposits'anegg, the front end of the nest frame 6 which is connectedto thisentrance door 10, is supported in its normal position against suchdepression by a toggle support 18, 1,4, the members of which are hingedtogetherat 15 with the lower endof`13 pivoted at 16 to one oi' thesides3 oil-the box frame, and the upper entl ofV 14 hinged at 17 to the frontend oi the nest vframe 6. The toggle is normally. retained in itsuprightposition by springs 18 yand 19.

This toggle strut is connected adjacent its articulation 15 by `a wire25:.to a short lever. y24` downwardly projecting from a rocking shaft 23mounted in the sides A3,011 whichv shaft is secured an arm 22 having anegg receiving receptacle .1 which, by a counterweight on the arm 22, isnormally supported ladjacent the end of a chute 20,

from the nest 7.

Thus, w'henthefhen has laid an egg that i draw back the short arm 24 tobreak the *i toggle 13,14, as shown by the ldot and dash lines in Fig.l, thereby deprivingthe front end of the nest frame 6 of its support.The i' weight of the hen on the nest then depresses that endol the nestframe and tilts the door 10to its closed position, las shown by dot anddash lines in Fig. 1. yIn this closed position it is retained bya latch26 pivoted at 28 to one oiE thel sides 3 and adapted .to engage a pin 27projecting `frein the adjacent side of the door 10.

As this door lO closes, the exit door 30 opens andthe hen having`performed its duty is free to leave the nest box.

`As soon `as the weight of the out-going hen passes the pivot 5 of thenest frame, its weight on the treadle `S depresses that end of the nestframe to its normal position, the upward movement of `the :front endlifting the latch 26 to release the entrance door by means of a rod 29connected to the front end of the` frame 6 and directed upward to engagethe latch and permit it to fall to the normal open position, in whichmovement the exit door 30 falls shut. Y In order that the eggs asdelivered from the nest may not encounter one another with the risk ofinjury, a circular egg magazine is mounted beneath the nest to turn on acentral pin 36. 'Ihis magazine is divided by partitions 37 yinto aseries of separate compartments, each adapted to receive an egg and itsedge rim is notched as at 3S that it may beV moved through an angulardistance corresponding to the space between the partitions 37 by theoscillating movement of the nest frame 6 on its pivot. A wire rod isslidably mounted adjacentl the rim of 35, which rod hask a projection 39adapted, when moved endwise, to successively engage the notches 38 ofthe magazine and rotate it through the space of one compartment, whenmoved endwise in one direction, and to lift over the incline of thenotches during its return movement. The ends of the rod 40 are connectedby a flexible line 41 to the opposite ends of the nest trame 6, so thatthe rod moves back and forth as that frame oscillates on its pivotConnection to the treadle end of the frame 6 is made to a resilienttongue 43 to equalize the distances from the pivot 5 and to maintain atension on the line 41.

To prevent an egg being delivered to the magazine after all thecompartments are lled, a stop` member 45 projects from the rim of themagazine 35, which projection,

after one complete revolution ofthe magazine, engages a stop pin 46upwardly projecting from the bottom 2 of the box trame and preventsrotation further. lVhen the lmagazine 35 cannot be/pulled round, the

\ treadle 8v cannot be depressed and consequently the latch 26 cannotbe"released by the rod 29 and the entrance door 10 remains closed. A iIn use, the nest boX is normally in the position shown bythe full linesin Fig. 1., with the entrance door open and the exit door closed, beingmaintainedin that position by the toggle support 13, 14, underk thefront end of the nest trame 6 pivoted at 5. The entrance of the hen tothe nest does not efect any change except that the presence of herweight on the nest is ready to effect the required movement. When theegg'is laid it rolls out through the chute 20, on the end of the rockingarm'22, which is counterweighted to maintain its position opposite theouter end of the chute. The weight of this egg overbalances thecounterweiglit'and rocks the shaft 23, which movement breaks the togglesupport 13, 14, as

indicated by thel dot and dash lines, and allows the front end of thenest frame 6, under the weight of the hen, to all, in which movement-itcloses and automatically latches the door 10 and simultaneously opensthe eXitdoor 30. e After the arm 22 has delivered the egg into one ofthe compartments of the magazine 35,'the rocking movement oit the nestframe 6 rotates the magazine'by means of the line 41 and rod 40 throughthe required distance to bring another space opposite the rocking lever22 `and restores t-he support 13, 14 to its upright position. 4 Havingnow particularly described my invention, I hereby declare that what Iclaim as new and desire to be protected in by Letters Patent, is: e lY 1.
